Marinobacterium lacunae sp. nov. isolated from estuarine sediment
(Springer, 2023)
A novel motile bacterium was isolated from a sediment sample collected in Kochi backwaters, Kerala, India. This bacterium is Gram negative, rod shaped, 1.0–1.5 µm wide, and 2.0–3.0 µm long. It was designated as strain ...
Porewater and solid phase speciation geochemistry of phosphorus in the Western Bay of Bengal: An assessment of depositional pathways
(Elsevier, 2023)
In this study, we used a combination of porewater phosphate and solid-phase P speciation to examine the present-day benthic biogeochemical cycling and pathways of phosphorus (P) deposition at four sites in the western Bay ...
Nature and hydrocarbon potential of organic matter in offshore Mahanadi Basin, east coast of India
(Springer, 2023)
Evaluating the hydrocarbon-generating potential of buried organic matter in marine sediments is critical in offshore oil/gas exploration. Organic matter sources, total organic matter content (TOC), and maturity state play ...
Relationship between coral bleaching and large-scale oscillations in the Lakshadweep archipelago
(Springer, 2023)
The coral reef ecosystems in the Lakshadweep Sea are among the least studied due to the dearth of in situ measurements. The objectives of this study were to compare the remote sensing datasets with the available in situ ...
Phthalate induced hormetic effect reveals susceptibility of gill compared to muscle tissue after depuration in commercially important fish (Etroplus suratensis)
(Elsevier, 2023)
Effect of Bis-2ethylhexyl phthalate (DEHP) on commercially important tropical fish pearl spot has not been demonstrated at environmental concentrations along with depuration. The species is estuarine, juvenile and difficult ...
Longshore currents on a meso-tidal beach of Goa, India - Measurements and improved formulae
(CSIR-NISCPR, New Delhi, 2023)
Field experiments in the surfzone were conducted on a meso-tidal beach stretch between Sinquerim and Baga off Goa on India's central west coast. Surfzone waves and currents were measured using an array of seabird wave and ...
Synthesis of pyrazolo[5,1-a]isoquinolines via C-H/N-H annulation of pyrazoles and alkynes with ruthenium(II) catalysts
(Springer, 2023)
A series of pyrazolo[5,1-a]isoquinolines have been synthesized by ruthenium(II)-catalyzed annulation of pyrazole derivatives with alkynes in the presence of Cu(OAc)2‧H2O and AgSbF6 producing pyrazolo[5,1-a]isoquinolines. ...
Mineralogical and geochemical variation in hydrothermal sulfides from Vienna Woods field, Manus Basin, Papua New Guinea: constraints on their evolution
(The Chinese Society of Oceanography, 2018)
Polymetallic sulfides from two hydrothermal chimneys and talus deposit from the Vienna Woods field of Manus Basin were studied for mineralogy, elemental composition, and S-isotope ratio to understand their evolution. The ...
Fucoxanthin and pheophytin-a from the marine algae Sargassum cinereum: Isolation, characterization and their feeding deterrent activity on Shrimps
(Indian Chemical Society, 2019)
Chemical investigation of the brown alga Sargassum cinereum collected from Goa coast, India led to the isolation of two bioactive pigments viz. pheophytin-a and fucoxanthin in a relatively good concentration. These pigments ...
Inverted sediments in the coastal Antarctic lake: Evidence of paleostorm?
(Elsevier, 2018)
The faunal (foraminiferal and diatom abundance) and sedimentological analysis was carried out on two cores collected from a coastal lake in the Vestfold Hills region of Antarctica. Out of a couple of cores collected from ...
